So, there is a bug where if you get a drop from a Hunt whilst having a fill inventory, you'll get an error, and the item goes into the abyss, lost forever. Unfortunately, I don't think those items are currently logged, so we can't even return them to you who might have encountered this.

There is a fix up, but it'll only go live on Monday, 19 Sep 2022.

tldr; Till 19 Sep 2022, make sure your inventory isn't full when you Hunt.

Sorry.
